目的：探讨超声骨刀在颌骨囊肿手术中的临床效果。方法：选取58例颌骨囊肿患者，随机分为A和B两组。A组采用超声骨刀手术，B组采用传统骨器械手术。观察2组手术时间、术中出血量、术后疼痛、伤口愈合及重要解剖结构（上颌窦黏膜、鼻腔黏膜、下颌神经管等）损伤情况。结果：A组术中出血量、术后疼痛程度及重要解剖结构损伤均显著小于B组；A组与B组手术时间无显著差异；创口均一期愈合。结论：超声骨刀安全、高效，降低了手术并发症。

Objective: To discuss the clinical effect and value of piezosurgery in the enucleation of cysts of jaws. Methods: 58 patients of jaw cysts were divided into two groups, 29 patients in group A were extracted by piezosurgery and 29 patients in group B were extracted by traditional instruments. The operation time, the amount of bleeding, the degree of postoperative pain, wound healing and complications were compared. Results: The amount of bleeding, the degree of postoperative pain and soft tissue damage in group A were significantly less than those in group B. No significant difference of operation time was found between the two groups. All the wounds in two groups were healed by first intention. Conclusions:Piezosurgery can effectively reduce the operative complications.
